NVIDIA Reiterates That It's Working On Wayland Support

Phoronix: NVIDIA Reiterates That It's Working On Wayland Support

While their proprietary Linux graphics driver right now only supports X11-based environments, NVIDIA has talked in the past about their plans to eventually support Wayland, and they've reaffirmed their intentions this week to supporting Wayland by their closed-source Linux GPU driver...

LoL
"Hey, devs, it will be appreciated if you develop your open code in the manner we like, but don't ask me more details because I can't speak about them. My contribution is limited to join in the mailing list saying that your code doesn't fit our "expectation" and then disappear the second after. Thanks."

I suppose the best way forward for Nvidia is to fork the X server
They don't provide any meaningful support for the open source drivers. Why should then the X server developers listen to them?
Nvidia, you leech!

BTW, do they really need to write their XWayland DDX? I thought that with Glamour everything they have to do is to write the OpenGL driver and XWayland will handle this transparently (together with direct rendering when that is written).

AMD's response: HEY! WE NEED TO MINIMIZE ENGINEERING COSTS! We could TALK about how we aren't supporting Wayland, but that would take time away from our engineer who has to make sure Catalyst won't support Wayland!

I don't see why the DDX used by the open source drivers matters to nVidia.

AFAIK it is not mandated to use the 'one-and-only' Wayland DDX, rather nVidia can add Wayland support to their own proprietary DDX to be used with the closed-source driver.

I think NVIDIAs current work on XWayland aimed at a certain way XWayland would be implemented in X11. Now with the new approach which sounds great, since you no longer need a patched xf86-video-{nouveau,intel,radeon} driver it has a drawback for NVIDIA. I'd assume GLX direct rendering would be needed to have games that don't use SDL 2 work on Wayland.

I'm surprised that NVIDIA is already working on XWayland support at this point with no xwayland code merged into mainline.

They are already making 2 drivers so have much higher engineering costs then AMD.
When they will make Catalyst userspace only they will probably have little to do to support Wayland / XWayland.
